OVERFLOW SLOP-HOPPER.

SPECIFICATION forming part of Letters Patent No. 428,986, dated May 27,1890.

Application filed November 1, 1886.

To all whom it may concern.-

Be it known that I, EDWARD W. WILLIAMS, of the city and county of SanFrancisco, State of California, have invented an Improved OverflowSlop-Hopper; and I do hereby declare that the following is a full,clear, and exact description thereof.

In the ordinary hopper, where no overflow is used, the perforations inthe strainer or bottom often become fouled or stopped up with grease andsediment, so that the water will not pass through. WVhen thisis thecase, unless it is cleaned and the perforations opened, the slop-waterwill run over the top of the hopper. This is not only an annoyance, butis positively unhealthy and liable to produce much damage, especially incities such as San Francisco, where the law requires every Waste-pipefrom a house to empty into a hopper before the waste water passes intothe sewer, so that every house is supplied with as many such hoppers asthere are wastepipes leading from it to the sewer.

My invention relates to that class of slophoppers provided with a sidepassage or over flow-spout; and it consists in the improved constructionand combination of parts, as hereinafter more fully described, andpointed out in the claim.

In the drawings referred to, Figure l is a perspective view of aslop-hopper with one side broken away, so as to show the overflowspout,perforated bottom, or strainer and trap space below the bottom. Fig. 2is a sectional elevation of the hopper, showing waste-passage to spacebelow the perforated bottom; and Fig. 3 is a front elevation of sidespout, perforated bottom, and bell of trap when detached from thehopper.

My invention is here represented in connection with a squareslop-hopper, such as are most generally used on this coast; but it canbe applied to the round or other style of hopper with equal facility.

A is the perforated plate or strainer which forms the bottom of thehopper, and to the under side of which the bell B, which traps the endof the waste-pipe O, is attached, so that when the strainer is in placethe bell covers the upper end of the pipe.

$erial No. 217,740. (No model.)

against the side of the hopper and form a semicircular spout extendingfrom a point a short distance below the top of the hopper down throughthe perforated bottom and communicating with the space below thestrainer. The upper end of this spout is open, so that when the waterhas raised in the hopper to the top of the spout it will waste down thespout in to the space below the strainer, and thus prevent the waterfrom overflowingthe top of the hopper. I prefer to make one or morelongitudinal slots a in the upright portion of the tube, so that thewater can Waste through the overflow before it rises to the top of thetube; but these slots are not absolutely necessary.

To prevent large floating substances from passing down theoverflow-spout, I secure a cap J over it, which is larger than the upperend of the spout, so as to trap its upper end. This will prevent thespout from becoming choked, and thus positively prevent the contents ofthe hopper from flowing over its top.

The device herein represented is simple and convenient, as it can beeasily lifted out bodily by using the spout as a handle. spout alsoserves as a vent to allow air to pass out when the Water passes throughthe strainer, thus increasing the eiiiciency of the strainer.

Having thus described my invention, what- I claim, and desire to secureby Letters Patent, is

The combination, with a slop-hopper having flaring upper end, of avertically-extending Wastc-pipe passing through the bottom of saidhopper, a removable perforated bottom provided on its under sidewith abell-shaped trap or cover fitting over the upper end of the wastepipe,and also having upon one of its side edges an elongated recess, aninclined concavo-convex spout in cross-section, or waste-pipe, havingits lower end registering with the recess of the bottom piece, and alsoThis having, laterally-extending flanges hearing against the inner sideof the hopper and provided upon its rounded face with a series oflongitudinal slots, and a perforated hood or cover fitting; over theupper end of the coneavo-eoiwex spent in cross-section, 01' over-.flow-pipe, said hood provided with downwardly-extending ears or lugsfor securing the same to the overflow-pipe, the hood, bottom, and bellbeing all connected and remov- 1o able together, substantially as setforth.

In witness whereof I have hereunto set my hand.
